Look-ahead timing prediction for multi-instance module (MIM) engineering change order (ECO)

Abstract:

Some embodiments determine a merged timing graph for a multi-instance module (MIM), wherein each node in the merged timing graph corresponds to a pin in the MIM, and wherein each node in the merged timing graph stores timing information associated with the corresponding pins in multiple instances of the MIM in a circuit design. The embodiments can then determine an ECO for the MIM based on the merged timing graph.
